Here we would like to obtain the NUT extension of a magnetized Reissner-Nordstrom black hole. To proceed, we employ the Ernst magnetization transformation to the RNTN spacetime as the seed. A sort of similar problem was investigated in [1]}, where the authors discussed a spacetime with NUT parameter surrounded by some weak magnetic fields. Aspects of the obtained spacetime solution in this paper are discussed, such as the black hole area and Hawking temperature. We then test the conjectured extremal Kerr/CFT correspondence in the new spacetime solution, where we are able to recover the extremal entropy by using the asymptotic symmetry group method [2]}, [3]}, [4]}.
